An elementary school student in Southampton was diagnosed with enterovirus — prompting worried officials to close the building Tuesday and Wednesday and scrub the entire fleet of buses.

“To prevent the spread of the virus, we have consulted with our district physician and the Elementary School will be closed to all students on Wednesday, Oct. 15 to undergo a thorough cleaning by an outside professional cleaning company,” Superintendent Scott Farina wrote on Southhampton Elementary School’s website.

The infected student was diagnosed over the weekend and stayed out of school on Tuesday.

He does not have the mysterious D68 strain of the virus, which has been causing severe respiratory illness in children and adults across the United States.

“I think the district was very smart to go ahead and close the building,” Marsha Kenny, the public affairs director for Southampton hospital, told 27 East.

“It can’t hurt to use antibacterial products on school surfaces. I think it is a good plan, because kids will be kids, and they are very comfortable touching and hugging and forgetting to wash their hands.”
